Unauthorized services charged on account, no refund to loyal customer???

I noticed an amount added to my monthly account fees for VAPS Hero 60 to the value of R69-00 per month, and after investigating found that this had been debited along with my contract fees for the past 4 months. I never signed on for this service, and disputed this with Vodacom. The service was suspended with immediate effect, however it has been 3 weeks since I requested a refund from Vodacom for these unauthorized charges. Still awaiting my refund of R276, but not hearing anything back from "my service provider".
